Abstract

The utility model relates to an electric automatic control device, particularly to an automatic closing controller. The technical scheme is that the automatic closing controller comprises a power supply, fuses, switches, a main control loop, and an automatic closing loop. The power supply is connected with the automatic closing loop through the fuses and the switches. The automatic closing loop comprises a time relay and an intermediate relay. The time relay and the intermediate relay are connected in parallel in the automatic closing loop. The time relay is connected in series with a normally-closed contact of the intermediate relay. The intermediate relay is connected in series with a normally-opened contact of the intermediate relay. The two ends of the normally-opened contact of the intermediate relay are connected in parallel with an all-powerful circuit breaker. The automatic closing loop is connected with the main control loop. A normally-opened contact of the time relay is connected in series with a unidirectional air switch and connected in the main control loop. The beneficial effects of the utility model are that by mounting the control device, a low-voltage general switch of a transformer realizes the automatic power transmission function; the workload is reduced; and the power consumption service level is increased.

Description

Automatic closing controller
Technical field
The utility model relates to a kind of power auto-control device, particularly a kind of automatic closing controller.
Background technology
After transformer high-voltage system blackout recovers, low-voltage load side cannot put into operation automatically, needs artificial power transmission.These faults often appear at some severe atmosphere, in the process of power transmission because the reasons such as traffic, weather also exist very large potential safety hazard, caused very large inconvenience to our work, increased employee's labour intensity, can not guarantee again very first time power transmission after fault recovery, greatly reduce our service level.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, and a kind of automatic closing controller that can alleviate work load, improve electricity consumption service level is provided.
The technical solution of the utility model is: comprise power supply, fuse, switch, main control loop and automatic closing loop, power supply is connected automatic closing loop with switch through overcurrent fuse, automatic closing loop comprises the time relay, auxiliary relay, the time relay, auxiliary relay access in parallel automatic closing loop, connect on the described time relay normally-closed contact of auxiliary relay, connect on the described auxiliary relay normally opened contact of auxiliary relay, the two ends universal circuit breaker in parallel of the normally opened contact of described auxiliary relay; Automatic closing loop connects main control loop, and the normally opened contact Series Sheet of the time relay accesses main control loop to air switch.
The beneficial effects of the utility model are: by control device is installed, make the low pressure master switch of transformer realize automatic power transmission function, reduce work load, improve electricity consumption service level.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model;
In upper figure: the normally opened contact SJ2 of the normally-closed contact ZJ1 of fuse RD, switch S, time relay sj, intermediate relay ZJ, auxiliary relay, the normally opened contact ZJ2 of auxiliary relay, universal circuit breaker DW, the time relay, one-way air switch QF.
Embodiment
By reference to the accompanying drawings 1, the utility model will be further described:
The utility model comprises power supply, fuse RD, switch S, main control loop, automatic closing loop, power supply is connected automatic closing loop with switch S through overcurrent fuse RD, automatic closing loop comprises time relay sj, intermediate relay ZJ, time relay sj, intermediate relay ZJ access in parallel automatic closing loop, the normally-closed contact ZJ1 of auxiliary relay connects on described time relay sj, connect in the described intermediate relay ZJ normally opened contact ZJ2 of auxiliary relay, the two ends universal circuit breaker DW in parallel of the normally opened contact ZJ2 of described auxiliary relay; Automatic closing loop connects main control loop, and the normally opened contact SJ2 Series Sheet of the time relay is to air switch QF access main control loop.
Operation principle:
1, the delay function that adopts time relay sj, carries out the temporal time of adjusting, staggering many transformer automatic closings to automatic closing controller, has effectively avoided transformer to start the impact to electrical network simultaneously.Such as the same high tension loop in certain community has ten transformers, adjusting the start-up time of controller, at high tension transmission, to stablize after 5 seconds, every transformer carries out automatic power transmission by 2 seconds intervals, can in 25 seconds, complete the power transmission to 10 transformers.
2, adopt intermediate relay ZJ to interlock the automatic closing loop of time relay sj, during guarantor's current earthing short circuit tripping operation, automatic closing controller is failure to actuate.
3, adopt main control loop to guarantee automatically to control to go the same way when manually having a power failure operation not carry out automatic closing to the self-locking of the interlocking of intermediate relay ZJ and intermediate relay ZJ.
4, adopt single-phase air switch QF to control physically separated of automatic closing controller and main closing device power unit, when guaranteeing maintenance or having other to need, manually exit automatic switching-on device.
5, automatic closing controller is not only applicable to the control to transformer universal circuit breaker DW, is also applicable to the power driven equipment of pushbutton enable.
This device is arranged on transformer, and by simulation, having a power failure can successful automatic reclosing, can significantly alleviate worker's work load, improves electricity consumption service level.

Claims (1)

1. an automatic closing controller, it is characterized in that: comprise power supply, fuse RD, switch S, main control loop and automatic closing loop, power supply is connected automatic closing loop with switch S through overcurrent fuse RD, automatic closing loop comprises time relay sj, intermediate relay ZJ, time relay sj, intermediate relay ZJ access in parallel automatic closing loop, the normally-closed contact ZJ1 of auxiliary relay connects on described time relay sj, the normally opened contact ZJ2 of auxiliary relay connects in described intermediate relay ZJ, the two ends universal circuit breaker DW in parallel of the normally opened contact ZJ2 of described auxiliary relay, automatic closing loop connects main control loop, and the normally opened contact SJ2 Series Sheet of the time relay is to air switch QF access main control loop.
